SargeBaldy reported that drag & drop file loading wasn't working. We checked and it turns out that it does work, but currently only for files under paths that are strictly MS-DOS 8.3 format. If there is any LFN directory on the path, the file won't get loaded.

This isn't intentional, it's just an oversight in my code caused by my having taken the advice of not entirely knowledgable people too literally, and then not personally testing D&D support before beta 4 launch. I'll try to get a patch out for this ASAP.
